Caption: Carpet beetle (Anthrenus sp.) larva on carpet fibres, coloured scanning electron micrograph (SEM). Carpet beetle larvae are a significant pest, feeding on animal materials including fur, feathers, hair, leather and other fabrics, and stored food products. The larvae can survive for two to three years indoors, before hatching into free-living adult beetles. The larvae are covered in hairs (setae) that can cause irritation to humans on contact with skin or if inhaled. Magnification x65 when printed 10cm wide.
